Ravens head coach John Harbaugh did not have any updates on running back Danny Woodhead or linebacker Za'Darius Smith at his Sept. 11 news conference, but it appears likely each will be out for some time after sustaining injuries during the Ravens' season-opening, 20-0 win at Cincinnati.

Harbaugh confirmed Woodhead is dealing with a hamstring injury, which had sidelined him late in the preseason as well. Woodhead returned to practice about a week before the season opener, but then injured his hamstring as he went out on a pass pattern late in the Ravens' first series at Cincinnati.

Woodhead had three catches for 33 yards -- leading the Ravens in receptions -- and also had one carry for 4 yards.
